Pros and cons

DeepSeek

Pros

  • Web chat and mobile apps are free
  • API output costs from $0.60 per 1M tokens (Flash, off-peak), well below most frontier providers
  • Open weights for V4 and earlier models on Hugging Face
  • 1M-token context and 384K max output on both API models
  • API works with both OpenAI and Anthropic SDKs and several coding agents

Cons

  • Peak-hour API rates are double the off-peak rates on weekday mornings UTC
  • deepseek-v4-pro does not support vision input
  • No image generation
  • Data is processed by a company based in China, which some organizations cannot accept

Opera Neon

Pros

  • Combines chat, browser actions, research and content creation in one browser rather than a separate extension.
  • Neon Do shows its plan and actions in real time and can be paused or taken over.
  • Wide model choice across OpenAI, Anthropic, Google, xAI and open-weight models on the Standard plan.
  • MCP connector and CLI let external agents such as Claude Code or n8n use a live browser session.
  • Credentials, passwords and card details are stated to stay on the device, and Opera says it does not train on user data.
  • Free VPN and ad blocker are included in the browser.

Cons

  • Full agentic features need the $19.90 per month Standard plan, higher than many AI add-ons.
  • Windows and macOS only; no Linux, iOS or Android version yet.
  • Neon Do uses cloud LLMs to plan, and page content is sent to Opera and OpenAI servers with 365-day retention.
  • Opera itself calls Neon an experimental agentic browser, so behaviour and plan limits may change.
